I think the photomask is made from electron beam lithography - this is too expensive and slow to do on each chip

[carlbatt]

That is not correct. These masks are made with something called a 'pattern generator' which is a direct write instrument. The cost of the mask is significant but this is the process used for a large majority of microelectronics.

Destroying potentially interesting videos with annoying and irrelevant background music is the M.O. of any good YouTuber. Don't you know that?

[brianmenendez]

they need to dump this stupid background music

[TheFlam3head]

Very cool vid! To the point and the music wasn't that bad. i actualy liked it. idk why some1 was complaining it was too gangsta. lmao.

No facemask?

That costs you at least 5% yield.

@seindich this drove me crazy. PHOTO = light, Lithos = stone, Graphis = writing.

Is there any project someone can do in their garage using this tech?

Background music a little cheesy guys - but great "cliff notes" video on photolithography! Good job - two thumbs up!

[againstas]

Very cheesy :P Loved it

@densepez See my response! It's correct!

@bethlier A nanometer (nm) is a billionth of a meter (1 x 10^-9 m).

[AdilFaranj]

Damn this looks expensive i wanna open my own photolithography business in Africa lol

[bethlier]

@densepez A nanometer is 1 trillionth of a meter. VERY SMALL!
